Atherosclerotic plaque rupture is the main cause of acute myocardial infarction and stroke, the two leading causes of death worldwide. Rupture of plaque tissue is a mechanical event, where plaque stress or strain locally exceeds its strength. Biomechanical studies agree with histopathological findings that a large lipid pool and thin fibrous cap...

At present, commercially available wearable sensors are only capable of tracking an individual’s physical activities and vital signs (such as heart rate). However, these devices fail to provide insight into fatigue itself. Fatigue is a broad term with many meanings. Fatigue in this paper refers to physiological changes where the muscle becomes...

The elicitation of user engagement is one of the current challenges of human-robot interaction, alongside with the identification of appropriate metrics to evaluate users' experience. Several studies focused on strategies aimed at maintaining engagement throughout an interaction, but limited research has been done on how to initiate it by...

Background: When a suspicious lesion is detected, a thorough examination is essential for the diagnostics of the lesion. Information about the nature and character of the lesion is crucial for the determination of the disease and an appropriate corresponding treatment plan. Taking a biopsy plays an important role in this examination. A biopsy is...

During endonasal pituitary surgery - an approach of skull base surgery - long slender instruments are inserted through the nose of the patient, in order to remove a pituitary lesion. One of the instruments which is repeatedly used is the surgical punch, which is able to remove pieces of bone in order to create access to the lesion. The drawback...

As the population ages and the know-how of the medical field progresses, the number of surgical interventions is rapidly expanding. Heart valve replacement surgery is no exception to this phenomenon; every year 280 000 heart valve replacement surgeries are performed worldwide.Despite the success of heart valve replacement surgeries, various...

The main goal of this master thesis is to develop a new low-cost radial air bearing system for the CT-scanner, which is currently expensive due to the strict tolerances on the large sized porous aerostatic radial air bearings as well as on the counter surface. This thesis has generated several potential low-cost air bearing system concepts. The...

Lifting an object by capillary forces is mostly done with a single liquid bridge which connects the target object to a probe. In this work the potential of capillary forces for soft-tissue manipulation is investigated; not only a single liquid bridge is used, but multiple bridges as well since capillary forces can be enhanced by contact...

A sit-snowboard is a weight supporting mechanism that allows people with lower extremity impairments to perform the sport of snowboarding. Comfort and control of the Twinrider (the only sit-snowboard on the market) are insufficient for advanced riders who reach higher speeds and ride more bumpy slopes. The goal of this study...

The work presented in the thesis was motivated by the history of cineplasty and aims to create a supportive system for the body powered upper limb prostheses. A mechanical signal (pulling) from a cineplastic site or a harness system (e.g. shoulder harness) is used to control a prosthetic device. These signals are often too weak to comfortably...

Access to prosthetics is very limited to many potential
users, while the need is high. There are two main reasons
for this that both are related to the production of prosthetics: the lack of skilled people and high costs. Minimized
assembly production using 3D printing could be a solution: no training is required, assembly takes only...

The goal of this study was to design a maternal phantom model specialized for experiments in which the stresses in the amniotic sac can be determined during fetoscopic procedures. These stresses caused by surgical procedures are believed to be the leading cause of post surgical pre-birth. Measuring these stresses indicates the quality of...

The twin-to-twin transfusion syndrome is a lethal hemodynamic imbalance between identical fetal twins as a result of vascular anastomoses in the monochorionic plate. With a fetoscopic laser photocoagulation the communicating vessels are interrupted, eliminating the inter-twin blood exchange. Since the first instruments were straight and rigid,...

In the high-tech semiconductor industry floating air conveyors are used to transport and position silicon substrates. An interesting point for improvement is to limit the loss of pressurized air as conveyors are only effective at the position of the substrate.
The goal of this research is to develop a local pneumatic valve, that is...

Cardiovascular diseases, in particular atherosclerosis, is currently the leading cause of death worldwide with increasing numbers due to an aging population. Recently, the first bioresorbable stent (BRS), Absorb GT1 (Abbott, USA) was approved by the FDA, consequently sparking enthusiasm in BRSs and degradable polymeric biomaterials. Polymeric...

With the aging population growing, the increasing prevalence of osteoarthritis (OA) seems inevitable. As a result, the number of joint replacements is expected to grow substantially within the next decade. Today’s hip replacements have the potential to function for more than 20 years, but due to risk factors such as aseptic loosening, the...
